The inner end of the beam is curved under and secured to a mold board D, said mold board having the usual plow point d. The excavating device resembles an ordinary low-share except that the usual land side 1s omitted.

A brace E extends rearwardlydiagonally tl, 'ELIJAH A. HOLLEN- 'glpartgoffthis specification whereinY fates a side elevationol a noLL-st'nnox, `or

The rear end of the draw bar is supported in the rear frame J, of the engine, or it may be secured to'any other part of the said engine. Clips K are secured to the front axle ofthe engine and a rod 7c is mounted to partially rotate therein. Said rod has a depending arm L, and an arm l, at right angles to said rod k. This arm L, is designed to impinge the road bed or surface being graded and acts as a brace in offsetting the lateral resistance due to the action of the plow or excavator as, it is thought, is obvious. The arm Z, has a connection M, with the front end'of the boiler which acts`as a stay to hold the arm L, Aagainst movement in one direction. When the; excavating apparatus is not Working the arm L may be elevated and supported in any-.convenient manner. 4

The excavating device delivers the material Vto anelevatoLor carrier extending transversely to the line of action of the ex-v cavator, and said carrier has a frame comprising the sect.ons 'N and O, suitably pivoted together at the` ointsfrt, *of ,The frames have rods P,to vv ich the rollers Q,

are applied,u said rollers being arranged in' the medium ofthe beveled gear Wheels T and U. The gear Wheel U is rotated by the shaft V, and said shaft is journaled in bearings applied to the sides of the frames. ord '1r to permit the outer conveyer fzrame to l. the boiler.

be adjusted with relation to the inner section of saidframe, the 'shaft is rovided withjoints, or if' preferred, a form o flexible shaft may be employed.

The outer section of the conveyer frame is held in adjusted position b iexible connections W, which are attache to the ears w, on the sides of the frame and said connections W, are wound on the drum X, journaled in the ends of the bars Y.v The bars are bolted to the engine boiler or other part of the engine and they have'braces y, also bolted to The lower ends ofthe bars Y, have longitudinally disposed internal racks y', in which the pinions y2, are adjustable. One of the roller rods projects' beyond the side of theframe and the pinions y2, are

mounted on said extensions and engage the racks 'y'. A hand wheel ya, is applied to rotate the pinions and said pinions are held in adjusted position by a dog 'z pivoted to a' side of the bar'Y, to engage t 1e pinion on the rod. The inner frame section is thus adjusted by the rack and`pinion device and the outer frame section is adjusted by means of the drum and iexible connections. =The inner end of the conveyer shaft and the sprocket wheel Z, mounted on it and the sprocket chain z, run thereover, are driven by the'sprocket wheel z which is substituted for an ordinary belt wheel on the drive shaft z2, of a traction engine. The bracket z8, serves as a bearing for the conve er shaft and said bracket is bolted to and cependsrom the engine boiler.

' In order that the conveyer may b e moved vertically as the excavating device 1s adjuslted, the brace E, is provided with an eye e2, through which a rod E2, extends, said rod be' connected at the rear to a leverE3, b

whic 4the rear end of said rod may be a shown in Fig. 2.

justed. As the rod E2, extends through the eye e2, and into the frame of the conveyer, it follows that any vertical movement of the rod E2 will be communicated to the conveyer, and hence the conveyer will move as the rod E2, is moved. f A brace E extends from the 'draw bar B transversely of the engine and 4said brace has its ollposite end connected to the lower end of t e rack bar Y as fully I claim: l

1. A road grader comprising an excavator, a draw-bar, said excavator having connection with said draw-bar, a conveyer adapted to receive the dirt upturncd by said excavator, means of connection between said exeavator and the grader frame, having an eye member, a rod member engaging the latter and said conveyer, and means for manually actuating said rod member. i

2. A road grader comprising an excavator, avdraw-bar formed of connected approximately E-shaped members spaced apart to receive between them the beam of said excavator, andhaving a bracket to which is connected the forward end of said excavator beam, means of connection between saidA ex# cavator, and the grader frame having an e e member, a conveyer adapted to receive t e dirt upturned bv'said excavator, a rod member extending through said eye member and connecting with said conveyer, and manually actuated means for said rod member.

3. A road grader comprising a conve er'or carrier in sections, means for effect-ing t e adjustment of the upper conveyer section and its, retention in position and additional ad'- justing means for the lower conveyer section, anexcavator arranged to deliver the upturned earth into said conveyer, and means for effecting the simultaneous' adjustment of said conveyer andsaid excavator for coperative actlon as set forth.

4. A road ader compris` means for adj ward end of said draw-bar in position, an excavator carried by said draw-bar, a conveyer for receiving the dirt fromV said excavator, means of connection between said excavator and the grader frame, amanually' actuated rod member and means'for ing said conveyer and said excavator om and by a common manually actuated means.
